System for controlling vehicle parameters

ABSTRACT

A system is provided which is capable of controlling one or more parameters of a vehicle, such as vehicle speed or engine RPM. The system involves communication between a transmitter and a controller. The transmitter has memory containing information that corresponds to a vehicle parameter setting. The information is operatively transmitted from the transmitter to the controller. Once the controller receives the information, the vehicle parameter setting is identified by the controller. When the setting is identified, the controller may adjust at least one mechanism on the vehicle so as modify the vehicle parameter accordingly. One scenario in which the parameter modification is generally provided is if the controller determines that the vehicle parameter is exceeding the identified setting, which corresponds to the vehicle being operated at a level higher than that intended for the vehicle operator.

FIELD

Embodiments of the invention relate to vehicles and controllingparameters of such vehicles.

BACKGROUND SECTION

Recreational type vehicles such as all-terrain vehicles (ATVs), utilityvehicles, motorcycles, golf carts, snowmobiles, and the like aregenerally operated by a wide range of people having varied levels ofexperience operating the vehicle. These people, or operators, tend tovary in a number of areas, including age, height, weight, and strength.These areas are cumulatively taken into account when determining howskilled a person may be in operating any one such vehicle. The skilllevel of the person is further influenced by the person's familiaritywith the particular vehicle.

It is often desirable to be cautious when permitting a person to operatea vehicle, especially when that person is not familiar with the vehicle.If not cautious, the person could experience problems when operating thevehicle, which if serious, could potentially lead to circumstances notonly affecting the condition of the vehicle, but also the safety of theoperator. One example of exhibiting caution may involve having theperson initially watch actual operation of the vehicle so that operatingtechniques can be learned through observation. Alternatively, one mayride with the person the first few times that the person operates thevehicle so that operating techniques can be learned through first-handpractice. Conversely, one may simply inform the person how the vehiclenormally operates, and/or describe what should be done for safe andeffective operation of the vehicle. In addition, the person may beinformed what should be done if and when certain events occur (e.g., theengine stalls).

While all of the above approaches can increase the probability that aperson's ride on the vehicle will be safe and uneventful, there is noguaranteeing this. As such, in certain instances, it may be desirable tolimit the amount of freedom operators have with respect to operatingvehicles, not only for the protection of the operator but also for theprotection of the vehicle. In particular, in these instances, it may bedesirable to eliminate any potential of deviating from parameters thatare recommended with respect to operating such vehicles. If a vehiclecould be configured to somehow limit the parameter automatically, itwould be beneficial to the owner and the operator (if the operator isnot the owner), as well as provide a valuable marketing tool formanufacturers of such vehicles. In addition, if this parameter limitingcould be adjusted for a plurality of different operators, it would be ofadditional benefit. Further, if this parameter limiting could beprovided for one or more of a number of different vehicle parameters, itwould be advantageous.

BRIEF SUMMARY SECTION

Certain embodiments of the invention provide a system that is capable ofcontrolling one or more parameters of a vehicle. The system involvescommunication between a transmitter and a controller. In certainembodiments, the transmitter is transportable, while the controller islocated on the vehicle. The transmitter has memory containinginformation. In certain embodiments, the information corresponds to onesetting for a vehicle parameter; however, it is to be appreciated thatthe information may alternatively correspond to a plurality of settings,with each setting corresponding to a different vehicle parameter. Whenthe transmitter is brought within a close distance of the controller,the information is operatively transmitted to the controller. Once thecontroller receives the information, the vehicle parameter settingcorresponding to the information is identified by the controller. Incertain embodiments, this identification is provided by comparing thetransmitted information to a set of information stored in memory of thecontroller. When the vehicle parameter setting is identified, in certainembodiments, the controller adjusts at least one mechanism on thevehicle to correspond with such parameter setting. This may involveremoving a restriction or limit on the vehicle parameter, or conversely,may involve adjusting the at least one mechanism on the vehicle so as toimpose a restriction or limit on the vehicle parameter. In this lattercase, the parameter restriction is generally provided if the controllerdetermines that the vehicle parameter setting is being exceeded, whichcorresponds to the vehicle being operated at a level which is higherthan the skill level of the operator. In certain embodiments, thecontroller is operatively coupled to a sensor that monitors the vehicleparameter and enables the controller to make the above determination.

Thecontroller is located on the vehicle and has memory. The memory stores aplurality of code sequences, with each code sequence corresponding to adifferent setting for a vehicle parameter. The transmitter includes anintegrated chip having preprogrammed memory storing a code sequence. Thecode sequence corresponds to one setting for the vehicle parameter. Thetransmitter is adapted for communication with the controller, with thecommunication involving transmission of a signal from the transmitter tothe controller. The signal contains the code sequence, and thecontroller is adapted to identify the one setting for the vehicleparameter corresponding to the code sequence. The sensor is electricallycoupled to the controller, and is adapted for measuring the parameter ofthe vehicle. The at least one mechanism is located on the vehicle and isadapted for adjustment so as to control the vehicle parameter. The atleast one mechanism is electrically coupled to the controller. Thecontroller is adapted to adjust the at least one mechanism so as tomodify the vehicle parameter if the vehicle parameter measured by thesensor exceeds the one setting corresponding to the code sequenceidentified by the controller.

DETAILED DESCRIPTION SECTION

The following detailed description is to be read with reference to thedrawings, in which like elements in different figures have likereference numerals. The drawings, which are not necessarily to scale,depict selected embodiments, but are not intended to limit the scope ofthe invention. It will be understood that many of the specific detailsof the vehicle incorporating the system illustrated in the drawingscould be changed or modified by one of ordinary skill in the art withoutdeparting significantly from the spirit of the invention.

An ATV 10 having a system in accordance with one embodiment of theinvention is illustrated in FIG. 1. The ATV includes a chassis,designated generally by reference numeral 20, to which the varioussystems and components of the vehicle are attached. These componentsinclude front wheels 12, rear wheels 14, handlebars 16 connected by asuitable steering linkage to the front wheels 12 for steering thevehicle, and a straddle-type seat 18 upon which the rider sits. Anengine and continuously variable transmission (CVT) are carried on thechassis 20, generally beneath the straddle-type seat 18 andsubstantially between a pair of footrests (only a left footrest 22 isvisible in FIG. 1). The invention is designed for use on vehicles suchas the ATV of FIG. 1, however, it may be used on other vehicles such asutility vehicles, golf carts, motorcycles, snowmobiles and the like.

The system described herein is capable of controlling one or moreparameters of a vehicle. A block diagram depicting an exemplaryembodiment of the system of the invention is shown in FIG. 2. Componentsof the system include a controller 30, a transmitter 32 or transceiver,and at least one mechanism 36. As shown, in certain embodiments, thesystem also includes a sensor 34. In certain embodiments, the controller30 includes a processor 38 with memory 40 and a transceiver 42. Thetransceiver 42 is shown as a part of the controller 30 for convenience;however, the invention should not be limited as such. It should beappreciated that the transceiver 42 could be separately located from thecontroller 30 and still function as intended with respect to theinvention as long as the transceiver 42 is located within transmittingdistance of the controller 30. The arrows connecting the systemcomponents are shown to illustrate the direction of outgoing signalsfrom each component. In certain embodiments, the transmitter 32 is atransponder (e.g., whereby receipt of a query signal is required beforea response signal is transmitted). As such, the controller 30 sendssignals to the transmitter 32 and the at least one mechanism 36. Thecontroller 30 receives signals from the transmitter 32 and, if included,the sensor 34. With respect to the functioning of components of thecontroller 30, when the transmitter 32 is brought within transmittingrange of the transceiver 42, the transceiver 42 transmits signals fromthe processor 38 to the transmitter 32 and sends signals received fromthe transmitter 32 to the processor 38. Accordingly, the processor 38sends signals to the at least one mechanism 36. In certain embodiments,these signals sent to the at least one mechanism 36 further depend onsignals being received by the processor 38 from the sensor 34. Thememory 40, while represented as separate from the processor 38, may begenerally integral with the processor 38. The memory 40 is representedin FIG. 2 as being separate from the processor 38 to demonstrate that itboth receives signals from and sends signals to the processor 38. Ofcourse, other components are connected to the controller 30 to aid inits function, as is well known in the art. The components shown in FIG.2 are merely those relevant to this exemplary embodiment. Suitableequivalents to the components described may be substituted as well.

In certain embodiments, the system of the invention is designed as an“add-on” device to a vehicle. Thus, the controller 30 as well as othernecessary components of the system are designed with the assumption thatsuch components would not be normally included in the standard design ofa vehicle and, as such, would need to be bought as a kit for suchvehicle. To be compatible to the vehicle, the controller 30 would needto either be compatible with existing wiring harnesses of the vehicle,or a new wiring harness for power supply would also need to be providedin such kit. Such a controller 30 is available from Sure PowerIndustries, Inc.

Certain embodiments of the system of the invention can be designed tofunction with the vehicle in any of a variety of different fashions. Forexample, the system can be designed to initially control the vehicle atan initial setting of vehicle parameter. As such, the system enables thevehicle to be operated up to a certain level, e.g., up to this initialsetting. In turn, when the transmitter 32 is brought within transmittingrange of the transceiver 42, the system facilitates the transfer ofinformation from the transmitter 32 to the controller 30. Subsequently,the system may modify how the vehicle can be operated based on thistransferred information. In certain embodiments, the transmitter 32 isan IC chip having memory and the information programmed or storedtherein is in the form of a code sequence. Such transmitters arecommonly known as RFID tag. The code sequence acquired by the controller30 during such transfer indirectly corresponds to the skill level of theperson with respect to operating the vehicle. Specifically, in certainembodiments, the code sequence corresponds to a specific setting for oneor more parameters of the vehicle, whereby the specific setting(s)correspond to the operator's skill level for operation of the vehicle.

In certain embodiments, the system is designed to control vehicle speed.With respect to this vehicle parameter, one or more skill levels (e.g.,“Beginner”, “Intermediate”, “Expert”, etc.) are designated for differentoperators of the vehicle. For every designated skill level, a specificsetting of the vehicle parameter is correspondingly assigned. Forexample, for an “Expert” skill level, the specific setting for thevehicle parameter, e.g., vehicle speed, is assigned, e.g., forforty-five miles per hour. In turn, a code sequence corresponding toeach assigned specific setting is stored in the memory 40 of thecontroller 30. In addition, one of the code sequences corresponding tothe specific settings of the vehicle parameter is stored in the memoryof the transmitter 32.

In certain embodiments, the vehicle is designed to be initially operatedat an initial specific setting corresponding to one of the codesequences stored in the memory 40 of the controller 30. Subsequently,the initial specific setting may be altered only if the operator bringsthe transmitter 32 within transmitting range of the transceiver 42. Forexample, the vehicle may be initially designed to operate at a“Beginner” skill level, in which the vehicle will only be permitted tooperate, e.g., at speeds, up to a certain level, e.g., twenty-five milesper hour, corresponding to the “Beginner” skill level. Subsequently, thevehicle may only be changed from such initial specific setting, andcorresponding code sequence and skill level, by an operator bringing thetransmitter 32 with stored code sequence within transmitting range ofthe transceiver. As such, when the transmitter 32 is brought within suchtransmitting range, the code sequence stored on the transmitter 32 istransmitted to the controller and identified. In turn, operability ofthe vehicle can be modified according to the transmitted code sequenceif different from the initial code sequence of the vehicle. In summary,the transmitter 32 would be used to transfer the code sequence to thecontroller 30 on the vehicle, and the controller 30 would associate suchcode sequence with the corresponding specific setting and control thevehicle accordingly.

Generally, as described herein, the code sequence stored in thetransmitter 32 indirectly corresponds to the operator skill level.However, it should be appreciated that other embodiments of theinvention can exist in which the code sequence stored in the transmitter32 directly represents the operator skill level. As such, for example,instead of the code sequence corresponding to a specific setting for aparameter of the vehicle, the code sequence can correspond to anoperator skill level (e.g., “Expert”). As such, the code sequence may bestored in memory of the transmitter 32, and the controller 30 would beconfigured to associate such code sequence with the correspondingoperator skill level, and in turn, select a corresponding specificsetting (e.g., twenty-five miles per hour) for one or more vehicleparameters (e.g., vehicle speed) based on the skill level of theoperator. Thus, by describing an exemplary embodiment herein whereby thecode sequence corresponds to a specific setting for one or more vehicleparameters, it is not done with the intention of limiting the inventionto such.

In certain embodiments, the transmitter 32 is transportable, while thecontroller 30 is located on a vehicle. In turn, when a person is allowedto operate the vehicle, the transmitter 32 is generally provided to him.In certain embodiments, as shown in FIG. 3A, the transmitter 32 isoperatively coupled to an ignition key 44 for the vehicle. As such, theperson would have the transmitter 32 whenever he or she is operating thevehicle. Thus, the transmitter 32 would be within transmitting range ofthe transceiver 42 when the vehicle is being operated since the ignitionkey 44 is placed proximate to the vehicle (in a ignition key slot) whenoperating the vehicle. The transmitter 32 may be positioned on the key46 in a plurality of different locations; however, it would generally bedesirable to position the transmitter 32 so as to not interfere with thefunctioning of the ignition key 44. As such, the transmitter 32 wouldlikely be positioned outside the cut area 46 of the key 44; however, theinvention should not be limited to such. Alternatively, one could havethe transmitter 32 located separate from the key 44 as shown in FIG. 3B.In such embodiments, the transmitter 32 can be part of a key ring orseparately coupled to such a key ring 48 for the ignition key 44 (asshown). However, it should be appreciated that in such embodiments wherethe transmitter 32 is located separate from the key 44, the transmitter32 may be removed by the operator so as to not function as intended withthe vehicle when the vehicle is operated. To decrease the potential ofthis occurring, embodiments involving the transmitter 32 beingoperatively coupled to the key 44 are more preferable.

In certain embodiments, each transmitter 32 will have its own outwardlyidentifying attribute. In turn, the attribute will help a personidentify the specific setting for the vehicle parameter corresponding tothe code sequence stored on the transmitter 32. As such, the transmitter32, based on the attribute, can be outwardly identified without havingto use it initially with a corresponding vehicle. In certainembodiments, the identifying attribute is with respect to color. Forexample, a transmitter storing a code sequence corresponding to aparameter setting for “Beginner” skill level may be red, while atransmitter storing a code sequence corresponding to a parameter settingfor “Expert” skill level may be green.

As mentioned herein, the code sequence transferred from the transmitter32 to the controller 30 is generally programmed in the memory of thetransmitter 32, and such code sequence corresponds with a vehicleparameter setting. In certain embodiments, such code sequencecorresponds with a plurality of settings, with each settingcorresponding to a different vehicle parameter. As such, each codesequence does not itself contain a specific setting for a vehicleparameter. Instead, each such code sequence corresponds to a specificsetting for a vehicle parameter only after the code sequences have beenpreviously assigned to such specific settings and subsequentlyprogrammed into the controller 30. As such, the specific settingsassigned and programmed into the controller 30 can subsequently bevaried as desired.

The code sequences can include any combination of characters (e.g., analpha/numeric combination) that can be identified by the controller 30.In certain embodiments, the code sequence is identified by thecontroller 30 via the processor 38 by comparing the code sequence to aset of code sequences stored in the memory 40 of the controller. Eachcode sequence, in certain embodiments, may also include a distinguishingportion. The purpose of including such a distinguishing portion (e.g.,an alpha/numeric combination) would be for the controller 30 todistinguish between two or more transmitters 32 having the sameparameter settings programmed therein. In turn, each controller 30 canbe configured to only work with transmitters 32 manufactured for thevehicle that the controller 30 is located on.

In accordance with certain embodiments of the invention, eachtransmitter 32 can be a Radio Frequency Identification (RFID) tag. RFIDhas become an important identification technology in applications suchas inventory management, security access, personnel identification,factory automation, automotive toll debiting, and vehicleidentification. In general, an RFID system includes an RFIDtransmitter-receiver unit and an RFID tag. With respect to theinvention, the controller 30 and transceiver 42 in combination are thetransmitter-receiver unit. In use, the RFID transmitter-receiver is usedto query the RFID tag, which may be located a distance from thetransmitter-receiver unit. Upon detection of the interrogating or querysignal, the RFID tag transmits a response signal back to the receiver.With respect to the invention, the response signal contains the codesequence. In certain embodiments, such code sequence corresponds tospecific settings for the one or more vehicle parameters. In certainembodiments, the code sequence may be further encoded or encrypted. As aresult, a decrypter or a corresponding database may be needed furtherfor deciphering the code sequence in order to then associate the codesequence with the corresponding specific setting.

RFID systems provide identification functions not found in otheridentification technologies such as optical indicia (e.g., bar code)recognition systems. For example, RFID systems may employ RFID tagscontaining read/write memory of several kilobytes or more. As such, thecode sequence stored on the transmitter 32 can be modified wheneverwarranted and there is adequate memory space to have the code sequencecorrespond to a specific setting for a vehicle parameter or, if desired,to have the code sequence correspond to specific settings for aplurality of vehicle parameters. The RFID tags may be readable at adistance and do not require direct line-of-sight view by a readingapparatus (e.g., base station or interrogator). In turn, thetransmitters 32 can be placed a distance away from the controller 30 andstill transmit the code sequence stored therein. Further, several suchRFID tags may be read by the RFID system at one time. As such, incertain embodiments, one or more transmitters 32 can be given to anoperator, whereby each transmitter 32 would store its own code sequencecorresponding to a specific setting for a different parameter for thevehicle, and whereby each code sequence from each transmitter 32 couldbe transmitted at one time.

RFID tags may be entirely passive (i.e., having no power supply), whichallows for availability in a small and portable package. However, thisidentification system would be only capable of operation over arelatively short range, limited by the size of an electromagnetic fieldused to supply power to the tags and to communicate with the tags. Suchelectromagnetic field typically is generated by an antenna. Suchantennas are generally integrated with the transmitter-receiver;however, they can just as well be mounted a transmittable distance fromthe transmitter-receiver. Alternatively, RFID tags may utilize a largeractive transmitter device affixed to an object to be monitored whichreceives a signal from the interrogator. The device receives the signal,then generates and transmits a responsive signal. The interrogationsignal and the responsive signal are typically radio-frequency (RF)signals produced by an RF transmitter circuit. Because active deviceshave their own power sources, they do not need to be in close proximityto an interrogator or reader to receive power via electromagnetic waves.

FIG. 4 illustrates a flow chart showing an embodiment of the operationof the invention. It should be appreciated that FIG. 4 illustrates onlyone exemplary embodiment, and steps in the flow chart could be exchangedor even in some cases eliminated without diverting from the spirit ofthe invention. As described above, FIG. 2 illustrates a block diagram ofthe invention in accordance with the flowchart, depicting each of thesystem components mentioned with respect to the flowchart of FIG. 4.Based on the functions described below for each of the components withinthe flowchart, it is contemplated that those skilled in the art wouldfind it obvious to be able to select appropriate devices andcorresponding manufacturers for each component.

As depicted in FIG. 4, the vehicle parameter controlling function of thesystem is initiated through communication between the transmitter 32 andthe controller 30. As mentioned above, in certain embodiments, thecommunication can be facilitated via RFID technology. As such, steps ofthe flowchart depicted in FIG. 4 are described in reference to such RFIDtechnology. However, it should be appreciated that other modes ofcommunication, direct or indirect (wireless) could be utilized insteadof or in combination with RFID. As such, by describing an embodiment forthe use of RFID technology, it is not done with the intention oflimiting the invention to such.

In using RFID for such communication, bringing the transmitter 32 withina certain distance of the controller 30 facilitates a signal being sentfrom the transmitter 32 to the controller 30. As described above, thetransmitter 32 could be passive, in which case it would need externalinfluence (e.g., an electromagnetic field) to operate (e.g., transmitsignals), or the transmitter 32 could be active, in which case it wouldhave a power source and need only be within transmitting range tooperate. If the transmitter 32 functions as a transponder, an initialstep 50 of the process would involve the controller 30 generating andtransmitting a query signal used to interrogate the transmitter 32. Inorder to facilitate this interrogation, the processor 38 would send thequery signal to the transceiver 42 that is in communication with theprocessor 38. Subsequently, the transceiver 42 would wirelessly transmitthe query signal to the transmitter 32, preferably by radio waves.

Step 52 involves the transmitted query signal being received by thetransmitter 32. In accordance with certain embodiments of the invention,the transmitter 32 is adapted to wirelessly receive the query signal andalso adapted to wirelessly transmit the code sequence upon its receiptof the query signal. As such, in response to the query signal beingreceived, the transmitter 32, also in step 52, transmits a code sequencestored therein to the controller 30 via the transceiver 42, preferablyby radio waves. The transceiver 42 would be adapted to distinguish,differentiate, or filter signals other than what they are intended toreceive. As mentioned herein, the transceiver 42 is in communicationwith the processor 38. As such, the code sequence transmitted from thetransmitter 32 to the transceiver 42 is subsequently transferred to theprocessor 38.

In certain embodiments of the invention, there may be multipletransceivers 42. For example, if more than one transmitter 32 isqueried, the controller 30 may have more than one transceiver 42 toreceive signals from the different transmitters 32, which signals wouldthen be sent to the processor 38 from the transceivers 42. This would bethe case for embodiments where a plurality of code sequencescorresponding to specific settings for more than one vehicle parameterare each stored on separate transmitters 32 instead of being all storedon one transmitter 32 as one code sequence. As such, the settings wouldbe transmitted from the corresponding transmitters 32, and via thetransceivers 42, subsequently transferred to the controller 30 inresponse to the query signal. This technique of receiving code sequenceswith corresponding transceivers 42 could be accomplished by selectingappropriate receiving ranges for each of the transceivers 42.Preferably, each of the transceivers 42 would also be adapted todistinguish, differentiate, or filter signals other than what they areintended to receive. Alternatively, if one wanted to limit the number oftransmitters 32 used, a single transmitter 32 storing a code sequencecan be given to the operator, whereby the stored code sequence wouldcorrespond to specific settings for a plurality of vehicle parameters.In such case, one transceiver 42 would be used to receive and transmitthe code sequence. Again, the transceiver 42 would preferably be adaptedto distinguish, differentiate, or filter signals other than what it isintended to receive.

In step 54, the code sequence is interpreted by the controller 30 viathe processor 38. If necessary, the controller 30 via the processor 38is adapted to segregate the information transmitted from the transmitter32 (e.g., if the code sequence contains one or more code sequences eachcorresponding to a specific setting for a different vehicle parameter).In certain embodiments, the code sequence is also logged, e.g., storedin the memory 40. The code sequence is interpreted using software and/ora database of identifying information. It is to be appreciated that suchsoftware can generally be incorporated in the processor 38. Using thesoftware, the code sequence would be cross-referenced with theinformation in the database, preferably held in the memory 40. In turn,the specific setting for the one or more parameters would be identifiedwhich corresponds to the code sequence. In certain embodiments, based onthe interpretation, messages or indications could be communicated to theuser via output elements (e.g., displays, annunciators, speakers, etc.on the vehicle) so that the operator would not mistake that the vehicle,when controlled per the parameter, was not working correctly. Forexample, the user could be notified via the output elements that thevehicle speed (parameter) will be set for a maximum speed (specificsetting) of thirty-five miles per hour. Such communication with the usercould be facilitated by the processor 38 being coupled to a controlpanel operatively connected to the output elements of the vehicle.

Additionally represented in the block diagram of FIG. 2 is a sensor 34,which is located on the vehicle. The sensor 34 is adapted to measure atleast one parameter of the vehicle 100, referenced as step 56. Incertain embodiments, the parameter measured is vehicle speed; however,it should be appreciated that many other parameters may be measured, forexample, engine RPM, engine temperature, etc. In addition, the sensor 34may reference one or more sensors each measuring a different parameterof the vehicle if the system is being used to control more than onevehicle parameter. With respect to the vehicle parameter being vehiclespeed on an ATV for example, the sensor 34 could be a wheel speed sensorthat monitors vehicle speed through wheel revolutions per unit time(e.g., minute or second). Further, in step 56, the measured vehicleparameter is subsequently transferred to the controller 30. The sensor34 would be operatively coupled to the controller 30 via the processor38. Sensor 34 need not be dedicated to controller 30. That is, sensor 34could be a preexisting RPM sensor or vehicle speed sensor that suppliessensed vehicle data to a speedometer. In such embodiments, speed datafrom the preexisting sensor could be routed to the processor 38 via aconnection to the vehicle speedometer.

In step 58, the measured vehicle parameter is, in turn, analyzed by thecontroller 30 via the processor 38. The processor 38 determines whetherthe measured vehicle parameter complies with the specific setting forthe vehicle (identified by the controller 30 via the processor 38 andmemory 40 in step 54). For example, if the measured vehicle parameterexceeds the specific setting for the vehicle parameter, the controller30 via the processor 38 would send a signal to the at least onemechanism 36 in step 60. If the system were being used to control morethan one vehicle parameter, the controller 30 via the processor mayaccordingly send a signal to more than one mechanism in step 60 tomodify the corresponding vehicle parameters. In certain embodiments, theat least one mechanism 36 is integral to the vehicle and can be modifiedto control the vehicle parameter. In step 62, the at least one mechanism36 is manipulated to control the vehicle parameter accordingly. Withrespect to the vehicle parameter being vehicle speed on an ATV forexample, the at least one mechanism 36 can be an electromechanicalsolenoid vacuum valve that is connected to the carburetor'sdiaphragm/slide mechanism. One type of such a system is disclosed inU.S. Pat. No. 3,596,642, entitled “Control System For Limiting OverloadAnd Overrunning Of An Internal Combustion Engine” and herebyincorporated by reference herein. By adjusting the valve accordingly,the RPM of the engine, and, therefore the vehicle speed can becontrolled to operate within certain desired levels. Many other types ofwell-known speed limiter systems, RPM limiter systems, etc. may be usedas the adjustable mechanism controlled by the controller. For instance,the RPM or speed limit mechanisms may be spark inhibitors available inthe vehicle's existing engine control module or capacitive dischargeignition system.

In certain embodiments, the adjustment to the at least one mechanism 36would be provided in a repeating fashion as shown in FIG. 4. Forexample, assume that the vehicle parameter is the vehicle speed on acarbureted ATV and that the adjustable mechanism is the solenoid vacuumvalve described above. When the vehicle is accelerated, the at least onemechanism 36 may need to be readjusted to limit the engine RPM. Afterthe measured vehicle parameter is found to comply in step 58 or afterthe at least one mechanism 36 is adjusted in step 62, the flowchartloops back to step 56, where the vehicle parameter is again measured bythe sensor 34. Subsequently, if the vehicle parameter were determined tobe below or above the specific setting, the at least one mechanism 36could be adjusted accordingly so that the vehicle is limited to acertain degree within the specific setting for the vehicle parameter.

FIG. 5 shows an exemplary embodiment of the invention, from which thegeneral proximity of the system components of FIG. 2 are described withrespect to the ATV 10 of FIG. 1. In certain embodiments as describedherein, the transmitter 32 is integrated to the ignition key (or coupledto the ignition key as or by a key ring) of the ATV 10. As such, whenoperating the vehicle, the transmitter 32 would be on or proximate tothe ignition key (not shown) placed in the ignition slot 66, which isgenerally located between the handlebars 16. As mentioned herein, thecontroller 30 communicates with the transmitter 32 via a transceiver 42.As described, the transceiver 42 can be mechanically coupled to thecontroller 42, but the invention should not be limited as such. Incertain embodiments, the controller 30 and transceiver 42 are energizedby the same power source, thus making it desirable to have both thecontroller 30 and the transceiver 42 located in close proximity to eachother. If the controller 30 and transceiver 42 are provided as a kit forthe ATV 10, their location on the ATV 10 will generally be dictated bywhere the wiring harnesses for powering the ATV 10 are located. Incertain embodiments, this location for the controller 30 and transceiver42 would generally be proximate to the engine of the ATV 10 (not visiblyshown but located generally beneath the seat 18 and substantiallybetween the pair of footrests; only the left footrest 22 is shown).However, if not provided as a kit, the controller 30 and transceiver 42can be located on the vehicle as desired so long as they are withintransmittable range of each other and the transceiver 42 is withintransmittable range of the transmitter 32 when the vehicle is beingoperated. The sensor 34 is located proximate to the vehicle mechanismthat it is sensing. For example, with respect to vehicle speed, thesensor 34 is located proximate to an axle of either the front wheels 12or rear wheels 14. The at least one mechanism 36 is located proximate tothe vehicle mechanism that is adjusted for controlling the vehicleparameter. For example, with respect to vehicle speed, the at least onemechanism 36 is located proximate to the engine (location previouslydescribed), e.g., at the solenoid vacuum valve connected to thecarburetor's diaphragm/slide mechanism (not visibly shown).
